1 Claim.

This invention I am about to describe has for an object to produce aburner of the type employing a liquid fuel of the character of crude oilsuch as petroleum and the like, in which certain volatile elements arepresent, capable of distillation therefrom upon the application of heatthereto, with a resultant residue of the nature of a highly carbonizedby-product of non-volatile 'quality.

A further object is to produce a burner for crude oil and similar fuelin which marked simplicity of construction and operation is obtained ascompared with other burners known to me.

These and other objects are attained in the burner described in thefollowing specification and illustrated in the accompanying drawing, inwhich:

Fig. 1 is a plan view of the burner embodying my invention. 7

Fig. 2 is a sectional view taken on the line 2--2 of Fig. 1.

Fig. 3 is a sectional view taken on the line 33 of Fig. 2.

Fig. 4 is a fragmental sectional view taken on the line 44 of Fig. 1.

The burner I have shown consists of a pan H which is provided with a riml2, a central opening I 3 which is flanged as shown at I4, an oilentrance opening IS, a gas exit opening I 6, residue discharge openingsI! and. I8, openings l9 and 20 which communicate through passage 2|, apriming opening 22, a heating dome 23 which covers openings l5, l1 andIS, a heating dome 24 which covers openings l6, l8 and 20, a burner 25which is mounted in flange M of opening [3, and a gas jet 26 whichconnects with gas exit l6 and discharges into opening I3.

Domes 23 and 24 covering openings l5, l1, l9, l6, I8 and 20, are sealedto the pan H at their lower edges by bolts 21. The pan, because of itsrim l2 and opening flange l4, may receive and retain a wicking 20preferably of incombustible characteristics, such as asbestos, by meansof which oil entering the pan through opening 22 will fill the pan andbecome absorbed by the wicking so as to permit of its being lighted forinitial heating of the burner domes, whereby gas generation will start.

The openings l5, l6, I9, and 20 are provided with short pipe lengthswhich extend upwardly into the domes 23 and 24, the respective pipes l5' and 20' of the openings l5 and 20 being shorter than the respectivepipes l6 and IS in openings l6 and I9, whereby inlet of oil throughopening l5 will permit of a normal oil level of the height of theshorter pipe I5 being maintained, somewhat as shown at oil level 29 inFig. 2, the higher pipe IS in opening l9 carrying ofi? the vapor andunvaporized oil into passage 2|, thence upwardly through the shortertube 28 in opening 20, such unvaporized oil also passing over with thevapor and possibly gradually accumulating until a normal level may be asshown at 30 is attained, the gas therefrom passing off through thehigher pipe l6 of opening l6, thence through the jet 26 and upwardly fordischarge from the orifices of burner 25, at which point the gas may beignited and the resultant flame caused to impinge the walls at the topsof the domes.

Obviously, the heated domes create gasification of the oil within them,initial gasification taking place in dome 23 and final gasificationtaking place in dome 24.

The residue in the oil within the domes gradually becomes such that novolatile part remains and the mass of the residue has become highlyimpregnated with carbon. It is essential that provision be made forremoval of this carbonized, nonvolatile residue. For this purpose theopenings I1 and I8, with their attached pipes are provided. A smallfeature which I have added, so that the valve control on the pipesopenings I1 and I8 may not be the only means for preventing oil.escaping and also so that automatic closure when all residue has beendrained from the domes, may be effected, is the ball valve 3| of openingI! and ball valve 32 of opening I8.

Having thus described my invention what I claim is:

An oil burner comprising a priming pan, a heating dome covering andsealing off a portion of said pan at each end thereof, a burner locatedon the pan between the domes and designed to direct its flames againstthe domes, each of said sealed ofi portions having an inlet and anoutlet, the outlet of one dome connecting with the inlet of the otherdome, the inlet of said one dome connecting with a source of oil supply,the outlet of the other dome connecting with the burner, said inletsextending within the domes to lower elevations than do the outletstherein, said pan outside the domes having an oil inlet for preliminaryheating purposes, said dome-sealed portions of the pan having drainageopenings therein, and means to close or open said openings as required.
